Please let us see some pictures when done. I have been trying to design a rear rack myself utilizing the lock and ride holes on my 570. I kind of like ChrisV removable rack. I am thinking of something similar only utilizing the tow bar receiver and the lock and ride holes up top so the whole thing is removable.I have been working on a carrier for the 570. Should have it ready in the next few weeks with the exception of powder coating. This mount used 4 of the lock-n-ride mounting holes and holds the tire over the rear at an angle. It will clear a factory rear bumper and still allow the use of the bed.
I would be interested in what you have in mind. I want something that would be able to be easily removed, so the rzr could be loaded in a truck bed, then just attach the tire and your good to go. I also use my rzr's bed around home for gathering fire wood and stuff so I would want to remove the tire at home too. Then there is also the need to get to the engine/air filter for mantinance . Lots of reasons to have a easy removable spare tire rack of some sorts. I think utilizing the hitch receiver is a start. Then maybe some bar bolted to the frame mounts on the rear of the bed that a pined bracket would be made as a spare tire rack. Other type of racks could be made utilizing this setup too.No problem. Plenty of pictures will follow. Going to make it from 1"x.083 wall tube.
If you want a quick remove carrier, there are many other options that can be done that don't use the Lock-n-Ride system. The design of this one is for a semi-permanent mount that is not removed all the time. I don't like the Lock-N-Ride mounts. I feel that they don't hold well. If you want one that you can remove, I will draw one up for you that can be remove by 3 pins and still use your hitch if you need to pull a trailer.
